Solution Overview
Problem
Conventional aerosol tanks face issues with inconvenient assembly and accidental leakage due to the need for precise force application during knob assembly, leading to potential misalignment and valve activation.
Innovation Solution
An aerosol tank valve joint device featuring a rotatable knob with an abutting block and elastic arm mechanism, allowing for connection and disconnection of the joint without axial movement, combined with structural features like annular steps and positioning portions to ensure stable assembly and prevent accidental valve activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the guide block interacts with the guide groove during assembly, then the knob can be mounted on the base, but a large pressure is required which may cause the knob to be pressed against the valve resulting in mistaken touch and leakage
Solution Approach 1:
The patent introduces a buffer block as an intermediary element between the knob and the guide block. This buffer block absorbs the assembly force and prevents direct transmission of excessive pressure to the valve, thereby avoiding accidental activation while still enabling successful assembly of the knob on the base.
Solution Approach 2:
The buffer block is pre-installed in the buffer groove before the knob is assembled onto the base. This beforehand cushioning arrangement ensures that when assembly force is applied, the buffer block is already in position to absorb and distribute the force, preventing it from being directly transmitted to the valve and causing accidental activation.
2Manufacturing precision
If the same force cannot be imposed every time during assembly, then consistency in assembly quality cannot be ensured, but varying force may lead to knob displacement and valve activation
Solution Approach 1:
The buffer block is pre-installed in the buffer groove before knob assembly. This beforehand cushioning ensures that regardless of the variation in assembly force applied, the buffer block will absorb excess force and prevent valve activation, while still allowing proper assembly to occur.
Solution Approach 2:
The buffer block acts as a mediator between the variable assembly forces and the valve. It absorbs the variability in applied force through elastic deformation, ensuring that the valve is never subjected to excessive force that would cause accidental activation, regardless of assembly consistency.
3Ease of operation
If the knob structure is simplified to eliminate axial movement, then assembly becomes more convenient, but the mechanism for connecting and disconnecting the joint must be redesigned
Solution Approach 1:
The patent changes the operational dimension from axial movement to rotational movement. The knob now rotates within the base rather than moving axially, and this rotational motion is converted into linear motion of the joint connection through the abutting block and buffer mechanism, achieving the desired function without axial displacement of the knob.
Solution Approach 2:
The patent introduces dynamic elements including the elastic buffer block that can deform and the rotatable knob that converts rotational motion into linear actuation of the joint. This dynamic mechanism allows the simplified knob structure to still achieve joint connection and disconnection through rotational rather than axial movement.

AI summary
An aerosol tank valve joint device and an aerosol tank. The aerosol tank valve joint device comprises a base, a knob, an elastic arm, and a joint. The elastic arm is provided on the base, the joint is provided on the elastic arm, the knob is axially positioned and is rotatably provided on the base in the circumferential direction, and an abutting block is provided on the side of the knob close to the joint. When the knob rotates in the circumferential direction, the abutting block can be driven to be close to and push the joint, or the abutting block can be driven to be away from the joint, such that the joint is reset under the elastic force effect of the elastic arm. The aerosol tank valve joint device of the present application can avoid leakage caused by mistaken touch of the valve during assembly, and has the advantages of being simple in structure and easy to assemble.
